How often should a motorcycle undergo an annual inspection?

For a newly purchased and registered motorcycle, the first four years require an inspection every two years. Starting from the fifth year, an annual inspection is required. Before the inspection, traffic violations must be addressed: Prior to the inspection, any traffic violations and penalty points must be cleared. After confirming there are no violations, bring your ID card, vehicle license, and go to the insurance company to apply for compulsory traffic insurance. Once these two preparations are completed, you can proceed to the motor vehicle inspection station for the inspection. Inspection process: When applying, the vehicle owner must fill out an application form and submit the vehicle license, compulsory traffic insurance certificate, vehicle and vessel tax payment or exemption certificate, and motor vehicle safety technical inspection certificate. The vehicle management office will confirm the vehicle, review the submitted documents, and issue the inspection compliance mark within one day of receiving the application.

Is it okay to mix 5w30 and 5w40?

5w30 and 5w40 should not be mixed. Reasons why 5w30 and 5w40 cannot be mixed: Different grades of engine oil have varying performance characteristics. Additionally, engine technical requirements differ among manufacturers, leading to different viscosity requirements for the oil. Effects of mixing 5w30 and 5w40: It increases the engine's operating resistance, resulting in insufficient engine power. Prolonged mixing can affect the engine's lifespan and also increase fuel consumption. Correct oil selection method: A comprehensive analysis should be conducted based on the vehicle's driving environment, the owner's driving habits, and the vehicle's maintenance manual to select the appropriate oil viscosity for better engine protection.

What does range mean?

The range displayed on the car dashboard refers to the estimated maximum distance the vehicle can travel at an economical speed with the remaining fuel in the tank. It is a calculated estimate provided by the car's instruments based on certain standards. How to check the car's range: Simply look at the odometer on the dashboard, which is indicated by "odo" followed by the unit "km". Its purpose is to inform the driver of the distance traveled. How to calculate the car's range: The car's range is calculated by dividing the remaining fuel in the tank by the vehicle's average fuel consumption. The fuel consumption is calculated by the dashboard based on the fuel used per 100 kilometers over the last 30 kilometers. The range is updated every kilometer, allowing it to gradually reflect the remaining fuel under different road conditions.

What Does a Car's Automatic Following System Rely on to Detect the Vehicle Ahead?

A car's automatic following system relies on the adaptive cruise control system of the vehicle ahead for detection. Detection method of the adaptive cruise control system: The driver activates the system using the control lever on the right side of the steering wheel, and the dashboard immediately indicates that the radar is ready. Then, the distance to the vehicle ahead is set using the buttons on the multifunction steering wheel, followed by setting the cruising speed via the cruise control lever. At this point, the driver can take their foot off the accelerator pedal. Introduction to the adaptive cruise control system: The adaptive cruise control system is an intelligent automatic control system developed from the existing cruise control technology. During vehicle operation, the distance sensor (radar) installed at the front of the vehicle continuously scans the road ahead, while the wheel speed sensors collect speed signals.

What is the use of the vehicle green book?

The 'Motor Vehicle Registration Certificate' is essentially the household registration booklet for the vehicle, commonly referred to as the 'green book' because of its green color. If you need to buy a car with installment loans, you will need to mortgage the Motor Vehicle Registration Certificate, also known as the green book. Small green book: In addition to the big green book, there is also the small green book, which generally refers to the tax payment certificate. After purchasing the car and paying taxes, including the vehicle and vessel tax, the tax authority will issue a tax payment certificate that includes information such as the license plate number and taxable quantity. You can declare and pay the tax yourself, or it can be paid by the insurance company when purchasing compulsory traffic insurance. The vehicle license is equivalent to the vehicle's ID card: Many people confuse the 'Motor Vehicle Registration Certificate' with the vehicle license. It's important to know that the 'Motor Vehicle Registration Certificate' is equivalent to the household registration booklet for the vehicle, while the vehicle license is equivalent to the vehicle's ID card. Therefore, when transferring vehicle ownership, the original owner (or the 4S shop) should proactively hand over the 'Motor Vehicle Registration Certificate' to the new owner. This certificate generally follows the actual owner.

Does a Car Need Water?

Cars do not need water; they require the use of antifreeze. Introduction to Antifreeze: Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year. How to Add Antifreeze: Open the engine hood where the antifreeze is located. The antifreeze reservoir cap is typically found under the engine hood. Then, check the antifreeze level. If it is below the standard level, it needs to be topped up. Precautions for Adding Antifreeze: When purchasing antifreeze for your car, always choose the appropriate type for your vehicle and avoid adding it indiscriminately.
